example 1
[0080]A 200 ml-capacity stainless steel pressure reactor equipped with a stirrer was provided as a first reactor. The reactor was charged with 200 g of 1-iodoperfluoroethane (C2F5I) as a telogen and charged with 10 g of copper powder as a metal catalyst, followed by heating to 100° C. While the temperature in the reactor was maintained at 100° C., tetrafluoroethylene was supplied as a taxogen while stirring the reaction mixture to pressurize the reactor until the pressure in the reactor became 1.2 MPa (gauge pressure).
[0081]Then, while the above temperature and pressure conditions were maintained, and while 1-iodoperfluoroethane (C2F5I) was supplied at a flow rate of 133 g / hr and tetrafluoroethylene was supplied at a flow rate of 5.5 g / hr, a reaction, mixture was discharged from the reactor at a rate of 138.5 g / hr. A telomerization reaction was thereby performed. The obtained reaction mixture was cooled to give 1,255 g of a first reaction mixture.

[0087]Then, while the above temperature and pressure conditions were maintained and while 1-iodoperfluoroethane (C2F5I) was supplied at a flow rate of 200 g / hr and tetrafluoroethylene was supplied at a flow rate of 5.0 g / hr, a reaction mixture was discharged from the reactor at a rate of 205.0 g / hr. A telomerization reaction was thereby performed. The obtained reaction mixture was cooled to give 2,254 g of a first reaction mixture.
